is there anyway to delete

[corticarte]

If by delete presets you mean delete the ones you can load when you create a new character or use a fantasia potion, you can just delete the files. My Games -> FINAL FANTASY XIV - A Realm Reborn -> files are named FFXIV_CHARA_01.dat, _02.dat, etc. etc. The numbers correspond with the numbers that appear in the list, so just check ingame which ones you want to get rid of, and delete accordingly.

That is, assuming you're not on a console. If so, I have no idea.

thanks for the info
